摘要
为满足对新能源消纳和电力供需平衡的要求,以新能源为主体的新型电力系统需要最大程度发挥负荷侧调节能力。针对当前用户侧调节能力未充分挖掘的问题,提出一种基于交互式实时电价机制的用电负荷优化方法。首先,基于区域电网内新能源总和建立广义标杆新能源出力曲线,提出一种基于改进时间序列形态相似度的用电负荷与广义新能源标杆曲线的源荷相似度计算方法,并构建负荷与电价的关联模型;进而提出基于源荷相似度的交互式实时电价机制引导用户参与响应;最后,构建多目标优化模型进行负荷优化。仿真结果表明,所提交互式实时电价机制的负荷优化效果更好,能够有效提高用户参与需求侧响应的积极性,相似度变化值能够准确衡量新能源与负荷曲线的相似度水平,使净负荷功率趋于平稳,促进新能源的高质量消纳。
To meet the requirements of accommodating new energy sources and balancing power supply and demand,a new type of power system dominated by new energy sources needs to maximize the load-side regulation capability.To address the problem of insufficient exploitation of load-side regulation capability,this study proposes an electricity load optimization method based on an interactive real-time electricity price mechanism.Firstly,a generalized benchmark new energy output curve is established based on the total new energy within a regional power grid.Secondly,a source-load similarity calculation method based on improved time series morphological similarity is proposed to calculate the similarity between electricity load and the generalized new energy benchmark curve,and a model for the correlation between load and electricity price is constructed.Then,an interactive real-time electricity price mechanism based on source-load similarity is proposed to guide user participation in response.Finally,a multi-objective optimization model is constructed for load optimization.Simulation results show that the proposed interactive real-time electricity price mechanism achieves better load optimization results,effectively increases user participation in demand-side response,and accurately measures the similarity between new energy and load curves.This approach stabilizes the net load power and promotes the high-quality integration of new energy.
